Figure 3

Robust features in NAWM and NAWM tracts. Features were extracted setting 64 as binning, and ICC was evaluated between the 4 (using different echo times) QSM reconstructions, setting 0.85 as threshold level. First row: line plot with number of robust features, total (a1) and considering the different feature categories (a2); second row: spider graph with the percentage of the number of robust features, total (b1) and considering the different feature categories (b2) (NAWM normal appearing white matter, ICC intraclass correlation coefficient, QSM quantitative susceptibility mapping, AF arcuate fasciculus, CST = cortico-spinal tract, FAT = frontal aslant tract, IFOF = inferior fronto-occipital fasciculus, OR = optic radiation, UF = uncinate fasciculus, FO = first-order, GL = grey level, GLCM = GL co-occurrence matrix, GLRLM = GL run length matrix, GLZM = GL zone matrix, NGTDM = neighbouring grey tone difference matrix, GLDM = GL dependence matrix).
